Abstract (en)
[origin: WO9819743A1] Biodegradable foam compositions for extinguishing class B fires are disclosed that may be in either a liquid concentrate or a powder concentrate form. The concentrates comprise: (1) a foaming group including a high-foaming surfactant such as an alkyl polyglycoside and a plurality of viscosity-reducing agents, for example, polyethylene glycol; and (2) a stiffening group including a water-soluble polymer such as a natural gum, e.g. xanthan gum, and a v iscosity-reducing agent. The powder concentrate further comprises a sorption agent.
